幽门螺杆菌相关性十二指肠溃疡短程三联治疗疗效的临床研究

目的：研究短程三联治疗幽门螺杆菌相关性十二指肠溃疡的疗效。方法：胃镜病理检查证实十二指肠单发溃疡活动期(A期)伴Hp感染的患分为一周组及维持组，均予三联抗幽门螺杆菌治疗。一周组治疗一周后即停止一切药物治疗，维持组则继续抗酸治疗四周，之后停药。两组均于治疗结束后四周及一年后复查胃镜及病理检查，了解所有患溃疡的愈合及幽门螺杆菌根除情况。结果：经三联抗幽门螺杆菌治疗结束后一年复查胃镜及病理检查，一周组溃疡愈合率83％，幽门螺杆菌根除率75％；维持组溃疡愈合率94％，幽门螺杆菌根除率80％。两组愈合率及幽门螺杆菌根除率相比较，差异无显性。经三联抗幽门螺杆菌治疗结束后一年，Hp根除组溃疡愈合率96％，Hp未根除组溃疡愈合率64％，差异有显性。结论：治疗十二指肠溃疡及预防复发，关健是根除Hp而不是长期抗酸治疗。     

角膜溃疡穿孔的修复与修复材料的选择

总结２１例用不同材料修复角膜穿孔的病例，修复材料分别为结膜瓣、硅胶板、断层自体皮片和同种异体角膜。结膜瓣遮盖仅２／３保存眼球，愈合后视力差，并发症多；硅胶板可在穿孔大、情况紧急时作暂时封孔保存眼球之用；自体断层皮片术后不久即溶解，角膜移植者７眼中６眼保存了眼球，且有５例植片透明，视力０．１以上。     

埃索美拉唑三联与奥美拉唑三联疗法治疗Hp阳性十二指肠溃疡对比研究

目的比较埃索美拉唑三联与奥美拉唑三联疗法治疗幽门螺杆菌（Hp）阳性十二指肠球部溃疡的临床疗效。方法将104例经内镜诊断并检测证实Hp阳性的十二指肠球部溃疡患者随机分为两组。埃索美拉唑组（52例）：埃索美托唑20mg＋阿莫西林1g＋克托霉素500mg，每日2次，共7d；奥美拉唑组（52例）：奥美拉唑20mg＋阿莫西林1g＋克拉霉素500mg，每日2次，共7d。疗程结束4周后复查胃镜并检测Hp，观察腹痛缓解率、溃疡愈合率、Hp根除率及用药后的不良反应等。结果埃索美拉唑组第1天和第2天腹痛缓解率分别为34．6％和59、6％，高于奥美托唑组的17.3％和38．5％（P〈0．05）。埃索美托唑组和奥美拉唑组溃疡愈合率分别为92.3％和88．5％，Hp根除率分别为88．5％和82．7％，差异无显著性（P〉0．05）。两组用药后不良反应少，有较好的安全性。结论埃索美拉唑三联疗法治疗Hp阳性的十二指肠溃疡安全有效．腹痛缓解速度优于奥美拉唑三联疗法。     

Relationship between the gastric myoelectric and mechanical activity in the genesis of ulcers in indomethacin-insulin-treated rats

We have proposed that gastric contractile activity mechanically induces ulcers in the nonsteroid antiinflammatory drug (NSAID)-treated rat. This study examines first the relationship between number (dose) of peristaltic contractions applied to the mucosa and the ulcer score. Second, it examines the relative roles of: altered gastric myoelectrical activity (MEA) resulting from indomethacin (Indo) pretreatment, insulin-induced gastric peristalsis, and a combination of the two in the generation of mucosal lesions. Third, it examines the effect of exogenous prostaglandin on the Indo-altered MEA and relates it to ulcerogenesis. Indo pretreatment increased gastric tone and MEA. In such animals, the dose of peristaltic contractions applied to the gastric wall was related to the ulcer score in a dose-dependent manner. Exogenous prostaglandin (PG) reversed the MEA effect of Indo and reduced ulceration. It is postulated that an altered smooth muscle state secondary to inhibition of prostaglandin synthesis (PG-S) renders the mucosa vulnerable to injury by peristaltic action.This study was supported by the Fast Foundation.     

A Case of a Patient with a Rectal Ulcer Who Had an Unusual Defecation Habit

Abstract: This case report describes a patient with a rectal ulcer who had an unusual defecation habit. Complete healing was recognized colonoscopically after the patient was instructed to break this habit. A polyp of the ascending colon was detected by a barium enema in a 37-year-old man complaining of anal bleeding. He was admitted to our division to undergo a polypectomy. At the time of the polypectomy, a round ulcer, measuring 1 cm in diameter, was detected on the right wall of the rectum 3 cm from the anal verge. A diagnosis of mucosal prolapse syndrome of the rectum could not be made because the patient did not exhibit the characteristic habit of excessive “straining” mentioned by patients with this syndrome, and no characteristic finding of fibromuscular obliteration was found on histological examination of biopsied specimens taken endoscopically from the lesion. Repeated history taking, however, revealed that the patient had the unusual habit of inserting his finger into his rectum after defecation. He broke this habit following instruction to do so. As a result, on colonoscopic examination 15 month later, the ulcer was found to have become a scar:     

美宝胃肠胶囊治疗胃炎和溃疡病的临床观察

目的：探讨美宝胃肠胶囊修复胃炎、胃溃疡等胃肠黏膜病变的治疗作用。方法：随机将40例具有胃黏膜病变的患者（慢性胃炎患者25例，消化性溃疡15例）分为两组：治疗组服用美宝胃肠胶囊及奥美拉唑治疗；对照组单用奥美拉唑治疗，根据临床症状改善情况及胃镜下黏膜修复情况综合评价疗效，并进行组间比效。结果：美宝胃肠胶囊联合奥美拉唑治疗组病人的临床症状改善率，优于单纯接受奥美拉唑治疗的对照组，治疗组的胃镜下病灶修复状况也优于对照组。结论：美宝胃肠胶囊对胃黏膜病变的修复与症状改善有良好的治疗作用。     

大鼠应激性溃疡与胃泌素、胰高血糖素和生长抑素的相关性研究

采用冷束缚法建立大鼠应激性溃疡模型，以探讨胃肠激素与应激性溃疡发病的相关性。实验组置于（４±２）℃环境，３Ｈ，对照组置于（１８±３）℃，３ｈ，分别检测不同时间血清胃泌素、胰高血糖素、生长抑素的水平。结果表明，实验组胃泌素、胰高血糖素水平明显高于对照组，生长抑素水平明显低于对照组。提示胃泌素、胰高血糖素、生长抑素可能从不同的角度参与了应激性溃疡的消长过程。

Gastric ulceration caused by heater probe coagulation

A double-contrast upper gastrointestinal examination on a woman who had undergone endoscopic heater probe therapy one day earlier for multiple arteriovenous malformations revealed shallow, irregular, and linear ulcers at the sites of heater probe coagulation. Multiple shallow ulcers may therefore develop as a direct complication of heater probe therapy. Radiologists should be aware of this complication to avoid diagnostic confusion in these patients.     

肝源性溃疡的临床观察

目的：研究乙肝后肝硬化患者消化性溃疡的临床特点及治疗转归，探讨内镜下止血及小剂量心得安对肝源性溃疡愈合的影响。方法：肝源性溃疡75例，观察其发病年龄、临床表现、溃疡部位、HP感染率、出血率及7d内止血率及溃疡愈合率等特点，随机分为治疗组37例，内镜下止血 心得安 泰胃美治疗，对照组38例，用维生素B6 泰胃美治疗；另外选单纯性消化性溃疡73例，随机对照2组36例，用维生素B6 泰胃美治疗，对照3组37例，内镜下止血 维生素B6 泰胃美治疗。结果：肝源性溃疡发病年龄较单纯性消化性溃疡晚10年，溃疡部位以复合性溃疡居多和并出血率高，内镜下止血 小剂量心得安可明显提高肝源性溃疡7d内止血率，促进肝源性溃疡愈合率，与对照组具有统计学意义(P＜0．01)。结论：肝源性溃疡难以治愈互易并出血，互以复合性溃疡多见，门静脉高压因素可能从中发挥作用，内镜下注射及喷洒止血剂及口服小剂量心得安及用制酸护肝治疗能有效止血，促进溃疡的愈合。
